The Gallic Wars were a series of military campaigns waged by the RomanproconsulJulius Caesar against several Gallic tribes. Rome's war against the Gallic tribes lasted from 58 BC to 50 BC and culminated in the decisive Battle of Alesia in 52 BC, in which a complete Roman victory resulted in the expansion of the Roman Republic over the whole of Gaul (mainly present-day France and Belgium). While militarily just as strong as the Romans, the internal division between the Gallic tribes helped ease victory for Caesar, and Vercingetorix's attempt to unite the Gauls against Roman invasion came too late.[6][7] The wars paved the way for Julius Caesar to become the sole ruler of the Roman Republic.

Although Caesar portrayed this invasion as being a preemptive and defensive action, most historians agree that the wars were fought primarily to boost Caesar's political career and to pay off his massive debts. Still, Gaul was of significant military importance to the Romans, as they had been attacked several times by native tribes both indigenous to Gaul and farther to the north. Conquering Gaul allowed Rome to secure the natural border of the river Rhine. The Gallic Wars are described by Julius Caesar in his book Commentarii de Bello Gallico, which remains the most important historical source regarding the conflict.[8]

His ambition was to conquer and plunder some territories to get himself out of debt, and it is possible that Gaul was not his initial target. It is more likely that he was planning a campaign against the Kingdom of Dacia,[9] located in the Balkans.

The countries of Gaul were civilized and wealthy. Most had contact with Roman merchants and some, particularly those that were governed by republics such as the Aedui and Helvetii, had enjoyed stable political alliances with Rome in the past.

The Romans respected and feared the Gallic tribes. Only fifty years before, in 109 BC, Italy had been invaded from the north and saved only after several bloody and costly battles by Gaius Marius. Around 62 BC, when a Roman client state, the Arverni, conspired with the Sequani and the Suebi nations east of the Rhine to attack the Aedui, a strong Roman ally, Rome turned a blind eye. The Sequani and Arverni sought Ariovistus’ aid and defeated the Aedui in 63 BC at the Battle of Magetobriga. The Sequani rewarded Ariovistus with land following his victory.[10][11][12] Ariovistus settled the land with 120,000 of his people. When 24,000 Harudes joined his cause, Ariovistus demanded that the Sequani give him more land to accommodate the Harudes people.[13][14] This demand concerned Rome because if the Sequani conceded, Ariovistus would be in a position to take all of the Sequani land and attack the rest of Gaul.[13] They did not appear to be concerned about a conflict between non-client, client and allied states. By the end of the campaign, the non-client Suebi under the leadership of the belligerent Ariovistus, stood triumphant over both the Aedui and their co-conspirators. Fearing another mass migration akin to the devastating Cimbrian War, Rome, now keenly invested in the defense of Gaul, was irrevocably drawn into war.

The Helvetii was a confederation of about five related Gallic tribes that lived on the Swiss plateau, hemmed in by the mountains as well as the Rhine and Rhone rivers. They began to come under increased pressure from German tribes to the north and east.[15]

By 58 BC, the Helvetii were well on their way in the planning and provisioning for a mass migration under the leadership of Orgetorix. Caesar mentions as an additional reason their not being able to in turn raid for plunder themselves due to their location. (De Bello Gallico, I, 2) They planned to travel across Gaul to the west coast, a route that would have taken them through lands of the Aedui, a Roman ally, and the Roman province of Transalpine Gaul.[15]

The Helvetii sent emissaries to neighboring tribes to negotiate peaceful transit. Orgetorix made an alliance with the Sequani chieftain Casticus and arranged the marriage of his daughter to an Aedui chieftain, Dumnorix. The three secretly planned to become kings of their respective tribes, and masters of the whole of Gaul (De Bello Gallico, I, 3). Orgetorix's personal ambitions were discovered and he was to be put on trial, with the penalty being death by fire if convicted. Orgetorix escaped with the help of his many debtors, but he died during his flight. However, the death of Orgetorix was "not without suspicion that he had decided upon death for himself" (committed suicide), as Caesar puts it (De Bello Gallico, I, 4).

Caesar dated their departure to the 28 March, and mentions that they burned all their towns and villages so as to discourage thoughts among undecided client tribes and enemies of occupying their vacated realm. (De Bello Gallico, I, 5 and 6).

Caesar was across the Alps in Italy when he received the news. With only a single legion in Transalpine Gaul, the endangered province, he immediately hurried to Geneva and ordered a levy of several auxiliary units and the destruction of the Rhone bridge. The Helvetii sent an embassy to negotiate a peaceful passage, promising to do no harm. Caesar stalled the negotiations for fifteen days, and used the time to fortify his position with a rampart nineteen miles long and a parallel trench (De Bello Gallico, I, 7 and 8).

When the embassy returned, Caesar refused their request and warned them that any forceful attempt to cross the river would be opposed. Several attempts were quickly beaten off. The Helvetii turned back and entered negotiations with the Sequani, and with Dumnorix of the Aeduans, for an alternate route.(De Bello Gallico, I, 8 and 9).

Leaving his single legion under the command of his second-in-command Titus Labienus, Caesar hurried to Cisalpine Gaul. Upon arrival, he took command of the three legions which were in Aquileia and enrolled two new legions, the Legio XI and the Legio XII. At the head of these five legions, he went the quickest way through the Alps, crossing territories of several hostile tribes and fighting several skirmishes en route (De Bello Gallico, I, 10).

Meanwhile, the Helvetii had already crossed the territories of the Sequani, and were busy pillaging the lands of the Aedui, Ambarri, and Allobroges. These tribes were unable to oppose them, and Roman allies asked for Caesar's help. Caesar obliged them and surprised the Helvetii as they were crossing the river Arar (modern Saône River). Three quarters of the Helvetii had already crossed, but one quarter, the Tigurine (a Helvetian clan), was still on the east bank. Three legions, under Caesar's command, surprised and defeated the Tigurine in the Battle of the Arar. The remaining Tigurini fled to neighboring woods (De Bello Gallico, I, 11 and 12).

After the battle, the Romans built a bridge over the Saône to pursue the remaining Helvetii. The Helvetii sent an embassy led by Divico, but the negotiations failed. For a fortnight, the Romans maintained their pursuit until they ran into supply troubles. Caesar, in the meantime, sent 4,000 Roman and allied Aedui cavalry to track the Helvetii, which suffered some casualties from only 500 Helvetii cavalry ("pauci de nostris cadunt"). Apparently Dumnorix was doing everything in his power to delay the supplies. Accordingly, the Romans stopped their pursuit and headed for the Aedui town of Bibracte. The tables were turned, and the Helvetii began to pursue the Romans, harassing their rear guard. Caesar chose a nearby hill to offer battle and the Roman legions stood to face their enemies (De Bello Gallico, I, 13 to 24).

In the ensuing Battle of Bibracte, the Celts and Romans fought for the better part of the day in a hotly contested battle with the Romans eventually gaining victory. Caesar writes that "the contest long and vigorously carried on with doubtful success." The defeated Helvetii offered their surrender, which Caesar accepted. However, 6,000 men of the Helvetian clan of the Verbigeni fled to avoid capture. Upon Caesar's orders, other Gallic tribes captured and returned these fugitives, who were executed. Those who had surrendered were ordered back to their homeland to rebuild it, and the necessary supplies were organized to feed them, as they were useful as a buffer between the Romans and the northern tribes. In the captured Helvetian camp, Caesar claims that a census written in Greek was found and studied: of a grand total of 368,000 Helvetii, of which 92,000 were able-bodied men, only 110,000 survivors were left to return home (De Bello Gallico, I, 25 to 29).

In 61 BC, Ariovistus, chieftain of the Suebi tribe and a king from the Germanic peoples, resumed the tribe’s migration from eastern Germania to the Marne and Rhine region.[16] Despite the fact that this migration encroached on Sequani land, the Sequani sought Ariovistus’ allegiance against the Aedui and, in 61 BC, the Sequani rewarded Ariovistus with land following his victory in the Battle of Magetobriga.[10][11][12] Ariovistus settled the land with 120,000 of his people. When 24,000 Harudes joined his cause, Ariovistus demanded that the Sequani give him more land to accommodate the Harudes people.[13][14] This demand 'concerned' Rome because if the Sequani conceded, Ariovistus would be in a position to take all of the Sequani land and attack the rest of Gaul.[13]

Following Caesar’s victory over the Helvetii, the majority of the Gallic tribes congratulated Caesar and sought to meet with him in a general assembly.[17]Diviciacus, the head of the Aeduan government and spokesmen for the Gallic delegation, expressed concern over Ariovistus’ conquests and the hostages he had taken.[18][19] Diviciacus demanded that Caesar defeat Ariovistus and remove the threat of a Germanic invasion otherwise they would have to seek refuge in a new land.[20] Not only did Caesar have a responsibility to protect the longstanding allegiance of the Aedui, but this proposition presented an opportunity to expand Rome’s borders, strengthen the loyalty within Caesar’s army and establish him as the commander of Rome’s troops abroad.[19][21]

The senate had declared Ariovistus a "king and friend of the Roman people" in 59 BC, so Caesar could not declare war on the Suebi tribe.[22] Caesar said that he could not ignore the pain the Aedui had suffered and delivered an ultimatum to Ariovistus demanding that no German cross the Rhine, the return of Aedui hostages and the protection of the Aedui and other friends of Rome.[23] Although Ariovistus assured Caesar that the Aedui hostages would be safe as long as they continued their yearly tribute, he took the position that he and the Romans were both conquerors and that Rome had no jurisdiction over his actions.[24] With the attack of the Harudes on the Aedui and the report that a hundred clans of Suebi were trying to cross the Rhine into Gaul, Caesar had the justification he needed to wage war against Ariovistus in 58 BC.[25]

Caesar, learning that Ariovistus intended to seize Vesontio, the largest town of the Sequani, commenced marching his troops toward Vesontio. Some of Caesar’s officers held their posts for political reasons only and had no war experience. Consequently, they suffered from poor morale which threatened Caesar’s campaign. Caesar challenged the officers and their legions, saying that the only legion he could trust was the 10th. With their pride on the line, the other legions followed the 10th’s lead, determined not to be outdone. Consequently, Caesar arrived in Vesontio before Ariovistus.[26][27]

Ariovistus sent emissaries to Caesar requesting a meeting. They met under a truce at a knoll on the plain. The truce was violated when Caesar learned that German horsemen were edging towards the knoll and throwing stones at his mounted escort.[28] Two days later, Ariovistus requested another meeting. Hesitant to send senior officials, Caesar dispatched Valerius Procillus, his trusted friend, and Caius Mettius, a merchant who had successfully traded with Ariovistus. Insulted, Ariovistus threw the envoys in chains.[29][30] Ariovistus marched for two days and made camp two miles behind Caesar, thus cutting off Caesar’s communication and supply lines with the allied tribes. Unable to entice Ariovistus into battle, Caesar ordered a second smaller camp to be built near Ariovistus’ position.[31] After the camp was completed, Caesar again challenged Ariovistus and was rewarded when Ariovistus attacked the smaller camp and was repulsed.

The next morning Caesar assembled his allied troops in front of the second camp and advanced his legions in triplex acies (three lines of troops) towards Ariovistus. Each of Caesar’s five legates and his quaestor were given command of a legion. Caesar lined up on the right flank.[32] Ariovistus countered by lining up his seven tribal formations. Caesar was victorious in the battle that ensued due in large part to the charge made by Publius Crassus. As the Germans began to drive back the Roman left flank, Crassus led his cavalry in a charge to restore balance and ordered up the cohorts of the third line. As a result, the whole German line broke and began to flee.[33][34] Most of Ariovistus’ one-hundred and twenty thousand men were killed. He and what remained of his troops escaped and crossed the Rhine, never to engage Rome in battle again. The Suebi camping near the Rhine returned home. Caesar was victorious.[35][36]

In 57 BC Caesar once again intervened in an intra-Gallic conflict, marching against the Belgae, who inhabited the area roughly bounded by modern-day Belgium. The Belgae had recently attacked a tribe allied with Rome and before marching out with his army to meet them, Caesar ordered the Remi and other neighbouring Gauls to investigate the Belgae's actions.[37] His army suffered a surprise attack in the battle of the Sabis while it was making camp near the river Sambre.

The Nervii advanced so quickly that Caesar did not have the time to organise his forces and nearly suffered a humiliating defeat. Caesar admits to losing all of his standards and most his centurions dead or felled by wounds. He himself was forced to take up a shield and personally rally his forces which were then threatened with envelopment and massacre. The strong stand by the X legion and the prompt arrival of reinforcements enabled Caesar to regroup, redeploy and eventually repulse the Nervii once the Atrebates and Viromandui were put to flight.[15]

Caesar remarked that the warlike Nervii refused to yield their ground even after the Atrebates and Virumandui had been put into disarray. When finally surrounded by Roman reinforcements the Nerviians continued fighting as a pitiless hail of missiles rained down on them from the many archers and peltasts Caesar had brought from overseas. The peltasts, slingers and archers were brought for the specific purpose of confounding the Gallic proclivity for shield wall tactics, mass attack and individual close combat.

The Nervii were especially renowned for skills at warfare. They ruled and subsisted by warfare and by taxing their dependent and client tribes while adhering to a heroic hoplitic tradition. These Gallic conventions were something Caesar exploited as often as he could.

Together with Caesar's prudent and unabashed use of fixed projectile weapons like the "scorpion" and light ballista, the archers and peltasts took a heavy toll on the densely packed Nervii, who themselves shunned all projectile weapons but the lance. It is recorded in Caesar's war commentaries that as the battle raged, the Nervii caught Roman javelins in flight and hurled them back at legionnaires and that although all were eventually slain, not one of the Nervii was seen to flee. As the grim fighting wore on, the Nervii refused to yield and mounds of the fallen formed ramparts and Boduognatus' fighters fought from atop these hills of dead, clashing with the pressing Roman ranks again and again.

The skill with which the veteran Roman legions executed their well practiced pilum barrage and gladius and scutum counter-attacks together with the prudent use of missile weapons was instrumental in defeating the skillful and daring Nervii and associated Belgae.

The Belgae suffered heavy losses and eventually surrendered when faced with the destruction of their towns. The Nervii were severely mauled and forced to flee; thereby all former client tribes surrendered to Caesar or likewise fled. Their absence gave Caesar control of most of what is now Belgium.

The following year, 56 BC, Caesar turned his attention to the tribes of the Atlantic seaboard, notably the Veneti tribe in Armorica (modern Brittany), who had assembled a confederacy of anti-Roman tribes. The Veneti were a seafaring people and had built a sailing fleet in the Gulf of Morbihan, requiring the Romans to build galleys and undertake an unconventional land and sea campaign. Eventually Caesar was able to subdue these tribes after a protracted land and sea campaign.

Caesar took his forces across the Rhine in 55 BC in a punitive expedition against the Germans, though the Suebi, against whom the expedition was mounted, were never engaged in battle. That same year, he then crossed the English Channel with two legions on his ships to mount a similar expedition against the Britons. The British adventure nearly ended in defeat when bad weather wrecked much of their fleet and the unfamiliar sight of massed chariots of the Britons caused confusion among their forces. Caesar did manage to secure a promise of hostages, though only two of them were actually sent. He withdrew, but returned in 54 BC with a much larger force that successfully defeated the powerful Catuvellauni, and forced them to pay tribute to Rome. The expeditions had little lasting effect, but were great propaganda victories for Caesar, keeping him in the public eye at home.

The campaigns of 55 BC and early 54 BC have caused controversy for many centuries. They were controversial even at the time among Caesar's contemporaries, and especially among his political opponents, who decried them as a costly exercise in personal aggrandizement. In modern times, commentators have been sharply divided between critics of Caesar's nakedly imperialist agenda and defenders of the benefits that the expansion of Roman power subsequently wrought in Gaul.

Discontent among the subjugated Gauls prompted a major uprising in the winter of 54–53 BC, when the Eburones of north-eastern Gaul rose in arms under their leader Ambiorix. Fifteen Roman cohorts were wiped out at Atuatuca Tungrorum (modern Tongeren in Belgium) and a garrison commanded by Quintus Tullius Cicero narrowly survived after being relieved by Caesar in the nick of time. The rest of 53 BC was occupied with a punitive campaign against the Eburones and their allies, who were said to have been all but exterminated by the Romans.

The uprising was, however, merely the prelude to a much bigger campaign led by Vercingetorix, chief of the Arverni tribe of central Gaul, who successfully united many Gallic tribes and states under his leadership. Recognizing that the Romans had an upper hand on the battlefield due to their panoply and training, he declined to give battle against them and instead fought a "scorched earth" campaign to deprive them of supplies. Caesar hurriedly returned from Italy to take charge of the campaign, pursuing the Gauls and capturing the town of Avaricum (modern city of Bourges) but suffering a defeat at Gergovia. Vercingetorix, instead of staying mobile and in the open, chose to hold out at Alesia (see Battle of Alesia). Caesar successfully besieged him and beat off a huge Gallic relief force who ran out of food and had to disperse. This effectively marked the end of the Gallic Wars, although mopping-up actions took place throughout 51 BC. A number of lesser rebellions took place subsequently, but Roman control of Gaul was not seriously challenged again until the 2nd century AD.

The primary historical source for the Gallic Wars is Caesar's Commentarii de Bello Gallico in Latin, which is one of the best surviving examples of unadorned Latin prose. It has consequently been a subject of intense study for Latinists, and is one of the classic prose sources traditionally used as a standard teaching text in modern Latin education.

The Gallic Wars have become a popular setting in modern historical fiction, especially that of France and Italy. Claude Cueni wrote a semi-historical novel, The Caesar's Druid, about a fictional Celtic druid, servant of Caesar and recorder of Caesar's campaigns. Morgan Llewelyn also wrote a book, Druids, about a Celtic druid who assisted Vercingetorix in his campaign against Julius Caesar. Similarly, Norman Spinrad's The Druid King follows the campaigns from Vercingetorix's perspective.[38] In addition, the comicAstérix is set shortly after the Gallic Wars, where the titular character's village is the last holdout in Gaul against Caesar's legions.

Indeed, the Gallic cavalry was probably superior to the Roman, horseman for horseman. Rome’s military superiority lay in its mastery of strategy, tactics, discipline, and military engineering. In Gaul, Rome also had the advantage of being able to deal separately with dozens of relatively small, independent, and uncooperative states. Caesar conquered these piecemeal, and the concerted attempt made by a number of them in 52 BC to shake off the Roman yoke came too late.

^That the Balkans were Caesar's original target is argued by several scholars, including: Penguin Classics The Conquest of Gaul: "Introduction", chapter 3 "The course of the war"[clarification needed], Adrian Goldsworthy, In the Name of Rome, chapter 8 "Caesar in Gaul". It is suggested by the provinces Caesar initially wanted for himself (Cisalpine Gaul and Illyricum) and supported by the initial placement of three of his four legions in Aquileia.

France
–
France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans 643,801 square kilometres and had a population of almost 67 million people as of January 2017. It is a unitary republic with the capital in Paris. Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse, during the Iron Age, what is now metropolitan France was inhabited by the Gauls, a Celtic people. The area was annexed in 51 BC by Rome, which held Gaul until 486, France emerged as a major European power in the Late Middle Ages, with its victory in the Hundred Years War strengthening state-building and political centralisation. During the Renaissance, French culture flourished and a colonial empire was established. The 16th century was dominated by civil wars between Catholics and Protestants. France became Europes dominant cultural, political, and military power under Louis XIV, in the 19th century Napoleon took power and established the First French Empire, whose subsequent Napoleonic Wars shaped the course of continental Europe. Following the collapse of the Empire, France endured a succession of governments culminating with the establishment of the French Third Republic in 1870. Following liberation in 1944, a Fourth Republic was established and later dissolved in the course of the Algerian War, the Fifth Republic, led by Charles de Gaulle, was formed in 1958 and remains to this day. Algeria and nearly all the colonies became independent in the 1960s with minimal controversy and typically retained close economic. France has long been a centre of art, science. It hosts Europes fourth-largest number of cultural UNESCO World Heritage Sites and receives around 83 million foreign tourists annually, France is a developed country with the worlds sixth-largest economy by nominal GDP and ninth-largest by purchasing power parity. In terms of household wealth, it ranks fourth in the world. France performs well in international rankings of education, health care, life expectancy, France remains a great power in the world, being one of the five permanent members of the United Nations Security Council with the power to veto and an official nuclear-weapon state. It is a member state of the European Union and the Eurozone. It is also a member of the Group of 7, North Atlantic Treaty Organization, Organisation for Economic Co-operation and Development, the World Trade Organization, originally applied to the whole Frankish Empire, the name France comes from the Latin Francia, or country of the Franks

Luxembourg
–
Luxembourg /ˈlʌksəmbɜːrɡ/, officially the Grand Duchy of Luxembourg, is a landlocked country in western Europe. It is bordered by Belgium to the west and north, Germany to the east and its culture, people and languages are highly intertwined with its neighbours, making it essentially a mixture of French and Germanic cultures. It comprises two regions, the Oesling in the north as part of the Ardennes massif. With an area of 2,586 square kilometres, it is one of the smallest sovereign states in Europe, Luxembourg had a population of 524,853 in October 2012, ranking it the 8th least-populous country in Europe. As a representative democracy with a monarch, it is headed by a Grand Duke, Henri, Grand Duke of Luxembourg. Luxembourg is a country, with an advanced economy and the worlds highest GDP per capita. Luxembourg is a member of the European Union, OECD, United Nations, NATO, and Benelux, reflecting its political consensus in favour of economic, political. The city of Luxembourg, which is the capital and largest city, is the seat of several institutions. Luxembourg served on the United Nations Security Council for the years 2013 and 2014, around this fort, a town gradually developed, which became the centre of a state of great strategic value. In the 14th and early 15th centuries, three members of the House of Luxembourg reigned as Holy Roman Emperors, in the following centuries, Luxembourgs fortress was steadily enlarged and strengthened by its successive occupants, the Bourbons, Habsburgs, Hohenzollerns and the French. After the defeat of Napoleon in 1815, Luxembourg was disputed between Prussia and the Netherlands and this arrangement was revised by the 1839 First Treaty of London, from which date Luxembourgs full independence is reckoned. In 1842 Luxembourg joined the German Customs Union, the King of the Netherlands remained Head of State as Grand Duke of Luxembourg, maintaining a personal union between the two countries until 1890. At the death of William III, the throne of the Netherlands passed to his daughter Wilhelmina and this allowed Germany the military advantage of controlling and expanding the railways there. In August 1914, Imperial Germany violated Luxembourgs neutrality in the war by invading it in the war against France and this allowed Germany to use the railway lines, while at the same time denying them to France. Nevertheless, despite the German occupation, Luxembourg was allowed to maintain much of its independence, in 1940, after the outbreak of World War II, Luxembourgs neutrality was again violated when the Wehrmacht of Nazi Germany entered the country, entirely without justification. A government in exile based in London supported the Allies, sending a group of volunteers who participated in the Normandy invasion. Luxembourg was liberated in September 1944, and became a member of the United Nations in 1945. Luxembourgs neutral status under the constitution formally ended in 1948, in 2005, a referendum on the EU treaty establishing a constitution for Europe was held

Belgium
–
Belgium, officially the Kingdom of Belgium, is a sovereign state in Western Europe bordered by France, the Netherlands, Germany, Luxembourg, and the North Sea. It is a small, densely populated country which covers an area of 30,528 square kilometres and has a population of about 11 million people. Additionally, there is a group of German-speakers who live in the East Cantons located around the High Fens area. Historically, Belgium, the Netherlands and Luxembourg were known as the Low Countries, the region was called Belgica in Latin, after the Roman province of Gallia Belgica. From the end of the Middle Ages until the 17th century, today, Belgium is a federal constitutional monarchy with a parliamentary system of governance. It is divided into three regions and three communities, that exist next to each other and its two largest regions are the Dutch-speaking region of Flanders in the north and the French-speaking southern region of Wallonia. The Brussels-Capital Region is a bilingual enclave within the Flemish Region. A German-speaking Community exists in eastern Wallonia, Belgiums linguistic diversity and related political conflicts are reflected in its political history and complex system of governance, made up of six different governments. Upon its independence, declared in 1830, Belgium participated in the Industrial Revolution and, during the course of the 20th century, possessed a number of colonies in Africa. This continuing antagonism has led to several far-reaching reforms, resulting in a transition from a unitary to a federal arrangement during the period from 1970 to 1993. Belgium is also a member of the Eurozone, NATO, OECD and WTO. Its capital, Brussels, hosts several of the EUs official seats as well as the headquarters of major international organizations such as NATO. Belgium is also a part of the Schengen Area, Belgium is a developed country, with an advanced high-income economy and is categorized as very high in the Human Development Index. A gradual immigration by Germanic Frankish tribes during the 5th century brought the area under the rule of the Merovingian kings, a gradual shift of power during the 8th century led the kingdom of the Franks to evolve into the Carolingian Empire. Many of these fiefdoms were united in the Burgundian Netherlands of the 14th and 15th centuries, the Eighty Years War divided the Low Countries into the northern United Provinces and the Southern Netherlands. The latter were ruled successively by the Spanish and the Austrian Habsburgs and this was the theatre of most Franco-Spanish and Franco-Austrian wars during the 17th and 18th centuries. The reunification of the Low Countries as the United Kingdom of the Netherlands occurred at the dissolution of the First French Empire in 1815, although the franchise was initially restricted, universal suffrage for men was introduced after the general strike of 1893 and for women in 1949. The main political parties of the 19th century were the Catholic Party, French was originally the single official language adopted by the nobility and the bourgeoisie

Switzerland
–
Switzerland, officially the Swiss Confederation, is a federal republic in Europe. It consists of 26 cantons, and the city of Bern is the seat of the federal authorities. The country is situated in western-Central Europe, and is bordered by Italy to the south, France to the west, Germany to the north, and Austria and Liechtenstein to the east. Switzerland is a country geographically divided between the Alps, the Swiss Plateau and the Jura, spanning an area of 41,285 km2. The establishment of the Old Swiss Confederacy dates to the medieval period, resulting from a series of military successes against Austria. Swiss independence from the Holy Roman Empire was formally recognized in the Peace of Westphalia in 1648. The country has a history of armed neutrality going back to the Reformation, it has not been in a state of war internationally since 1815, nevertheless, it pursues an active foreign policy and is frequently involved in peace-building processes around the world. In addition to being the birthplace of the Red Cross, Switzerland is home to international organisations. On the European level, it is a member of the European Free Trade Association. However, it participates in the Schengen Area and the European Single Market through bilateral treaties, spanning the intersection of Germanic and Romance Europe, Switzerland comprises four main linguistic and cultural regions, German, French, Italian and Romansh. Due to its diversity, Switzerland is known by a variety of native names, Schweiz, Suisse, Svizzera. On coins and stamps, Latin is used instead of the four living languages, Switzerland is one of the most developed countries in the world, with the highest nominal wealth per adult and the eighth-highest per capita gross domestic product according to the IMF. Zürich and Geneva have each been ranked among the top cities in the world in terms of quality of life, with the former ranked second globally, according to Mercer. The English name Switzerland is a compound containing Switzer, a term for the Swiss. The English adjective Swiss is a loan from French Suisse, also in use since the 16th century. The name Switzer is from the Alemannic Schwiizer, in origin an inhabitant of Schwyz and its associated territory, the Swiss began to adopt the name for themselves after the Swabian War of 1499, used alongside the term for Confederates, Eidgenossen, used since the 14th century. The data code for Switzerland, CH, is derived from Latin Confoederatio Helvetica. The toponym Schwyz itself was first attested in 972, as Old High German Suittes, ultimately related to swedan ‘to burn’

Roman Republic
–
It was during this period that Romes control expanded from the citys immediate surroundings to hegemony over the entire Mediterranean world. During the first two centuries of its existence, the Roman Republic expanded through a combination of conquest and alliance, by the following century, it included North Africa, most of the Iberian Peninsula, and what is now southern France. Two centuries after that, towards the end of the 1st century BC, it included the rest of modern France, Greece, and much of the eastern Mediterranean. By this time, internal tensions led to a series of wars, culminating with the assassination of Julius Caesar. The exact date of transition can be a matter of interpretation, Roman government was headed by two consuls, elected annually by the citizens and advised by a senate composed of appointed magistrates. Over time, the laws that gave exclusive rights to Romes highest offices were repealed or weakened. The leaders of the Republic developed a tradition and morality requiring public service and patronage in peace and war, making military. Many of Romes legal and legislative structures can still be observed throughout Europe and much of the world in modern nation states, the exact causes and motivations for Romes military conflicts and expansions during the republic are subject to wide debate. While they can be seen as motivated by outright aggression and imperialism and they argue that Romes expansion was driven by short-term defensive and inter-state factors, and the new contingencies that these decisions created. In its early history, as Rome successfully defended itself against foreign threats in central and then northern Italy, with some important exceptions, successful wars in early republican Rome generally led not to annexation or military occupation, but to the restoration of the way things were. But the defeated city would be weakened and thus able to resist Romanizing influences. It was also able to defend itself against its non-Roman enemies. It was, therefore, more likely to seek an alliance of protection with Rome and this growing coalition expanded the potential enemies that Rome might face, and moved Rome closer to confrontation with major powers. The result was more alliance-seeking, on the part of both the Roman confederacy and city-states seeking membership within that confederacy. While there were exceptions to this, it was not until after the Second Punic War that these alliances started to harden into something more like an empire and this shift mainly took place in parts of the west, such as the southern Italian towns that sided with Hannibal. In contrast, Roman expansion into Spain and Gaul occurred as a mix of alliance-seeking, in the 2nd century BC, Roman involvement in the Greek east remained a matter of alliance-seeking, but this time in the face of major powers that could rival Rome. This had some important similarities to the events in Italy centuries earlier, with some major exceptions of outright military rule, the Roman Republic remained an alliance of independent city-states and kingdoms until it transitioned into the Roman Empire. It was not until the time of the Roman Empire that the entire Roman world was organized into provinces under explicit Roman control

Gauls
–
The Gauls were Celtic peoples inhabiting Gaul in the Iron Age and the Roman period. Their Gaulish language forms the branch of the Continental Celtic languages. The Gauls emerged around the 5th century BC as the bearers of the La Tène culture north of the Alps, Gaul was never united under a single ruler or government, but the Gallic tribes were capable of uniting their forces in large-scale military operations. They reached the peak of their power in the early 3rd century BC, after this, Gaul became a province of the Roman Empire, and the Gauls were culturally assimilated into a Gallo-Roman culture, losing their tribal identities by the end of the 1st century AD. The Gauls of Gallia Celtica according to the testimony of Caesar called themselves Celtae in their own language, the name Gaul itself may be derived from Latin Galli, or it may be derived from the Germanic word Walha. Gaulish culture developed out of the Celtic cultures over the first millennia BC, the Urnfield culture represents the Celts as a distinct cultural branch of the Indo-European-speaking people. The spread of iron working led to the Hallstatt culture in the 8th century BC, the Hallstatt culture evolved into the La Tène culture in around the 5th century BC. The Greek and Etruscan civilizations and colonies began to influence the Gauls especially in the Mediterranean area, Gauls under Brennus invaded Rome circa 390 BC. Following the climate deterioration in the late Nordic Bronze Age, Celtic Gaul was invaded in the 5th century BC by tribes later called Gauls originating in the Rhine valley. Gallic invaders settled the Po Valley in the 4th century BC, defeated Roman forces in a battle under Brennus in 390 BC and raided Italy as far as Sicily. A large number of Gauls served in the armies of Carthage during the Punic Wars, in the Aegean world, an invasion of Eastern Gauls appeared in Thrace, north of Greece, in 281 BC. However, according to the Roman legend of the gold of Delphi. One king Cerethrius invaded the Thracians, while another Gallic king Bolgios invaded Macedonia and Illyria where he killed the Macedonian king Ptolemy Keraunos, in 278 BC Gaulish settlers in the Balkans were invited by Nicomedes I of Bithynia to help him in a dynastic struggle against his brother. They numbered about 10,000 fighting men and about the number of women and children. They were eventually defeated by the Seleucid king Antiochus I, in a battle where the Seleucid war elephants shocked the Galatians. While the momentum of the invasion was broken, the Galatians were by no means exterminated and continued to demand tribute from the Hellenistic states of Anatolia to avoid war,4,000 Galatians were hired as mercenaries by the Ptolemaic Egyptian king Ptolemy II Philadelphus in the 270 BC. According to Pausanias, soon after arrival the Celts plotted “to seize Egypt, ”, Galatians also participated at the victorious in 217 BC Battle of Raphia under Ptolemy IV Philopator, and continued to serve as mercenaries for the Ptolemaic Dynasty until its demise in 30 BC. They sided with the renegade Seleucid prince Antiochus Hierax, who reigned in Asia Minor, after the defeat, the Galatians continued to be a serious threat to the states of Asia Minor

Germanic peoples
–
The Germanic peoples are an ethno-linguistic Indo-European group of Northern European origin. They are identified by their use of Germanic languages, which diversified out of Proto-Germanic during the Pre-Roman Iron Age, the term Germanic originated in classical times when groups of tribes living in Lower, Upper, and Greater Germania were referred to using this label by Roman scribes. Tribes referred to as Germanic by Roman authors generally lived to the north, in about 222 BCE, the first use of the Latin term Germani appears in the Fasti Capitolini inscription de Galleis Insvbribvs et Germ. This may simply be referring to Gaul or related people, the term Germani shows up again, allegedly written by Poseidonios, but is merely a quotation inserted by the author Athenaios who wrote much later. Somewhat later, the first surviving detailed discussions of Germani and Germania are those of Julius Caesar, from Caesars perspective, Germania was a geographical area of land on the east bank of the Rhine opposite Gaul, which Caesar left outside direct Roman control. This usage of the word is the origin of the concept of Germanic languages. In other classical authors the concept sometimes included regions of Sarmatia, also, at least in the south there were Celtic peoples still living east of the Rhine and north of the Alps. Caesar, Tacitus and others noted differences of culture which could be found on the east of the Rhine, but the theme of all these cultural references was that this was a wild and dangerous region, less civilised than Gaul, a place that required additional military vigilance. Caesar used the term Germani for a specific tribal grouping in northeastern Belgic Gaul, west of the Rhine. He made clear that he was using the name in the local sense and these are the so-called Germani Cisrhenani, whom Caesar believed to be closely related to the peoples east of the Rhine, and descended from immigrants into Gaul. Caesar described this group of both as Belgic Gauls and as Germani. Gauls are associated with Celtic languages, and the term Germani is associated with Germanic languages, but Caesar did not discuss languages in detail. It has been claimed, for example by Maurits Gysseling, that the names of this region show evidence of an early presence of Germanic languages. The etymology of the word Germani is uncertain, the likeliest theory so far proposed is that it comes from a Gaulish compound of *ger near + *mani men, comparable to Welsh ger near, Old Irish gair neighbor, Irish gar- near, garach neighborly. Another Celtic possibility is that the name meant noisy, cf. Breton/Cornish garm shout, however, here the vowel does not match, nor does the vowel length ). Others have proposed a Germanic etymology *gēr-manni, spear men, cf. Middle Dutch ghere, Old High German Ger, Old Norse geirr. However, the form gēr seems far too advanced phonetically for the 1st century, has a vowel where a short one is expected. The term Germani, therefore, probably applied to a group of tribes in northeastern Gaul who may or may not have spoken a Germanic language

Iberians
–
The Iberians were a set of peoples that Greek and Roman sources identified with that name in the eastern and southern coasts of the Iberian peninsula, at least from the 6th century BC. The Roman sources also use the term Hispani to refer to the Iberians, the term Iberian, as used by the ancient authors, had two distinct meanings. One, more general, referred to all the populations of the Iberian peninsula without regard to ethnic differences and this non-Indo-European cultural group spoke the Iberian language from the 7th to the 1st century BC. Other peoples possibly related to the Iberians are the Vascones, though related to the Aquitani than to the Iberians. The Iberian culture developed from the 6th century BC, and perhaps as early as the fifth to the third millennium BC in the eastern and southern coasts of the Iberian peninsula, the Iberians lived in villages and oppida and their communities were based on a tribal organization. The Iberians in the Spanish Levant, were more urbanized than their neighbors in the central, the peoples in the central and northwest regions were mostly Celtic, semi-pastoral and lived in scattered villages, though they also had a few fortified towns like Numantia. They had a knowledge of writing, metalworking, including bronze, in the centuries preceding Carthaginian and Roman conquest, Iberian settlements grew in social complexity, exhibiting evidence of social stratification and urbanization. This process was aided by trading contacts with the Phoenicians, Greeks. The settlement of Castellet de Banyoles in Tivissa was one of the most important ancient Iberian settlements in Catalonia that was discovered in 1912, also, the Treasure of Tivissa, a unique collection of silver Iberian votive offerings was found here in 1927. Lucentum was another ancient Iberian settlement, as well as Castelldefels Castle, mausoleum of Pozo Moro near the town of Chinchilla de Monte-Aragón in Castile-La Mancha seems to mark the location of another big settlement. Sagunto is the location of an ancient Iberian and later Roman city of Saguntum, Greek colonists made the first historical reference to the Iberians in the 6th century BC. They defined Iberians as non-Celtic peoples south of the Ebro river, the Greeks also dubbed as Iberians another people in the Caucasus region, currently known as Caucasian Iberians. It is not known if there had any type of connection between the two peoples. The Iberians traded extensively with other Mediterranean cultures, Iberian pottery and metalwork has been found in France, Italy, and North Africa. The Iberians had extensive contact with Greek colonists in the Spanish colonies of Emporion, Rhode, Zakynthos, the Iberians may have adopted some of the Greeks artistic techniques. Statues such as the Lady of Baza and the Lady of Elx are thought to have made by Iberians relatively well acquainted with Greek art. Thucydides stated that one of the three tribes of Sicily, the Sicani, were of Iberian origin, though Iberian at the time could have included what we think of as Gaul. The Iberians also had contacts with the Phoenicians, who had established colonies in southern Andalucia

Julius Caesar
–
Gaius Julius Caesar, known as Julius Caesar, was a Roman politician, general, and notable author of Latin prose. He played a role in the events that led to the demise of the Roman Republic. In 60 BC, Caesar, Crassus, and Pompey formed an alliance that dominated Roman politics for several years. Their attempts to power as Populares were opposed by the Optimates within the Roman Senate. Caesars victories in the Gallic Wars, completed by 51 BC, extended Romes territory to the English Channel, Caesar became the first Roman general to cross both the Channel and the Rhine, when he built a bridge across the Rhine and crossed the Channel to invade Britain. These achievements granted him unmatched military power and threatened to eclipse the standing of Pompey, with the Gallic Wars concluded, the Senate ordered Caesar to step down from his military command and return to Rome. Caesar refused the order, and instead marked his defiance in 49 BC by crossing the Rubicon with the 13th Legion, leaving his province, Civil war resulted, and Caesars victory in the war put him in an unrivalled position of power and influence. After assuming control of government, Caesar began a programme of social and governmental reforms and he centralised the bureaucracy of the Republic and was eventually proclaimed dictator in perpetuity, giving him additional authority. But the underlying political conflicts had not been resolved, and on the Ides of March 44 BC, a new series of civil wars broke out, and the constitutional government of the Republic was never fully restored. Caesars adopted heir Octavian, later known as Augustus, rose to power after defeating his opponents in the civil war. Octavian set about solidifying his power, and the era of the Roman Empire began, much of Caesars life is known from his own accounts of his military campaigns, and from other contemporary sources, mainly the letters and speeches of Cicero and the historical writings of Sallust. The later biographies of Caesar by Suetonius and Plutarch are also major sources, Caesar is considered by many historians to be one of the greatest military commanders in history. Caesar was born into a family, the gens Julia. The cognomen Caesar originated, according to Pliny the Elder, with an ancestor who was born by Caesarean section. The Historia Augusta suggests three alternative explanations, that the first Caesar had a head of hair, that he had bright grey eyes. Caesar issued coins featuring images of elephants, suggesting that he favored this interpretation of his name, despite their ancient pedigree, the Julii Caesares were not especially politically influential, although they had enjoyed some revival of their political fortunes in the early 1st century BC. Caesars father, also called Gaius Julius Caesar, governed the province of Asia and his mother, Aurelia Cotta, came from an influential family. Little is recorded of Caesars childhood, in 85 BC, Caesars father died suddenly, so Caesar was the head of the family at 16

Vercingetorix
–
Vercingetorix was a king and chieftain of the Arverni tribe, he united the Gauls in a revolt against Roman forces during the last phase of Julius Caesars Gallic Wars. Vercingetorix came to power after his designation as chieftain of the Arverni at the oppidum Gergovia in 52 BC. He immediately established an alliance with other Gallic tribes, took command and combined all forces and he won the Battle of Gergovia against Julius Caesar in which several thousands Romans and allies died and Caesars Roman legions withdrew. However, Caesar had been able to exploit Gaulish internal division to easily subjugate the country, at the Battle of Alesia, the Romans besieged and defeated his forces. In order to save as many of his men as possible he gave himself to the Romans and he was held prisoner for five years. In 46 BC, as part of Caesars triumph, Vercingetorix was paraded through the streets of Rome, Vercingetorix is primarily known through Caesars Commentaries on the Gallic War. To this day, Vercingetorix is considered a hero in Auvergne. The generally accepted view is that Vercingetorix derives from the Gaulish ver-, cingeto-, in his Life of Caesar, Plutarch renders the name as Vergentorix. He made use of the factionalism among the Gallic elites, favoring certain noblemen over others with political support, the revolt that Vercingetorix came to lead began in early 52 BC while Caesar was raising troops in Cisalpine Gaul. Undeterred, Vercingetorix raised an army of the poor, took Gergovia and was hailed as king and he made alliances with other tribes, and having been unanimously given supreme command of their armies, imposed his authority through harsh discipline and the taking of hostages. He adopted the policy of retreating to natural fortifications, and undertook an early example of a scorched earth strategy by burning towns to prevent the Roman legions from living off the land. Vercingetorix scorched much of the land marching north with his army from Gergovia in an attempt to deprive Caesar of the resources and safe haven of the towns, however, the capital of the Bituriges, Avaricum, a Gallic settlement directly in Caesars path, was spared. Due to the strong protests, naturally defendable terrain, and apparently strong man-made reinforcing defenses. Upon reaching Avaricum however, the Romans laid siege and eventually captured the capital, the next major battle was at Gergovia, capital city of the Arverni and Vercingetorix. During that battle, Vercingetorix and his warriors crushed Caesars legions and allies, Vercingetorix then decided to follow Caesar but suffered heavy losses during a cavalry battle and he retreated and moved to another stronghold, Alesia. In the Battle of Alesia, Caesar built a fortification around the city to besiege it, the relief came in insufficient numbers, estimates range from 80,000 to 250,000 soldiers. Vercingetorix, the leader, was cut off from them on the inside. However, the attacks did reveal a point in the fortifications and the combined forces on the inside

Auxilia
–
The Auxilia constituted the standing non-citizen corps of the Imperial Roman army during the Principate era, alongside the citizen legions. By the 2nd century, the Auxilia contained the number of infantry as the legions and in addition provided almost all of the Roman armys cavalry. The auxilia thus represented three-fifths of Romes regular land forces at that time, like their legionary counterparts, auxiliary recruits were mostly volunteers, not conscripts. The Auxilia were mainly recruited from the peregrini, free provincial subjects who did not hold Roman citizenship and constituted the vast majority of the population in the 1st and 2nd centuries. In contrast to the legions, which only admitted Roman citizens, reliance on the various contingents of non-Italic troops, especially cavalry, increased when the Roman Republic employed them in increasing numbers to support its legions after 200 BC. The Julio-Claudian period saw the transformation of the Auxilia from motley levies to a corps with standardised structure, equipment. By the end of the period, there were no significant differences between legionaries and auxiliaries in terms of training, and thus, combat capability. Auxiliary regiments were stationed in provinces other than that in which they were originally raised, for reasons of security. The regimental names of many auxiliary units persisted into the 4th century, but by then the units in question were different in size, structure, despite its formidable strength, the legion had a number of deficiencies, especially a lack of cavalry. Around 200 BC, a legion of 4,200 infantry had an arm of only 300 horse. In addition the legion lacked missile forces such as slingers and archers, until 200 BC, the bulk of a Roman armys cavalry was provided by Romes regular Italian allies, commonly known as the Latin allies, which made up the Roman military confederation. This was Romes defence system until the Social War of 91–88 BC, the Italian forces were organised into alae. Since a pre-Social War consular army always contained a number of legions and alae. The overall cavalry element, c. 12% of the force, was greater than in most peninsular Italian forces. The Roman/Latin cavalry was sufficient while Rome was in conflict with other states in the mountainous Italian peninsula, which also disposed of limited cavalry resources. The decisive Roman victory at Zama in 202 BC, which ended the war, owed much to the Numidian cavalry provided by king Massinissa, from then, Roman armies were always accompanied by large numbers of non-Italian cavalry, Numidian light cavalry and, later, Gallic heavy cavalry. For example, Caesar relied heavily on Gallic and German cavalry for his Conquest of Gaul, as the role of native cavalry grew, that of Roman/Latin cavalry diminished. In the early 1st century BC, Roman cavalry was phased out altogether, after the Social War, the socii were all granted Roman citizenship, the Latin alae abolished, and the socii recruited into the legions

Plutarch
–
Plutarch was a Greek biographer and essayist, known primarily for his Parallel Lives and Moralia. He is classified as a Middle Platonist, Plutarchs surviving works were written in Greek, but intended for both Greek and Roman readers. Plutarch was born to a prominent family in the town of Chaeronea, about 80 km east of Delphi. The name of Plutarchs father has not been preserved, but based on the common Greek custom of repeating a name in alternate generations, the name of Plutarchs grandfather was Lamprias, as he attested in Moralia and in his Life of Antony. His brothers, Timon and Lamprias, are mentioned in his essays and dialogues. Rualdus, in his 1624 work Life of Plutarchus, recovered the name of Plutarchs wife, Timoxena, from internal evidence afforded by his writings. A letter is still extant, addressed by Plutarch to his wife, bidding her not to grieve too much at the death of their two-year-old daughter, interestingly, he hinted at a belief in reincarnation in that letter of consolation. The exact number of his sons is not certain, although two of them, Autobulus and the second Plutarch, are often mentioned. Plutarchs treatise De animae procreatione in Timaeo is dedicated to them, another person, Soklarus, is spoken of in terms which seem to imply that he was Plutarchs son, but this is nowhere definitely stated. Plutarch studied mathematics and philosophy at the Academy of Athens under Ammonius from 66 to 67, at some point, Plutarch took Roman citizenship. He lived most of his life at Chaeronea, and was initiated into the mysteries of the Greek god Apollo. For many years Plutarch served as one of the two priests at the temple of Apollo at Delphi, the site of the famous Delphic Oracle, twenty miles from his home. By his writings and lectures Plutarch became a celebrity in the Roman Empire, yet he continued to reside where he was born, at his country estate, guests from all over the empire congregated for serious conversation, presided over by Plutarch in his marble chair. Many of these dialogues were recorded and published, and the 78 essays, Plutarch held the office of archon in his native municipality, probably only an annual one which he likely served more than once. He busied himself with all the matters of the town. The Suda, a medieval Greek encyclopedia, states that Emperor Trajan made Plutarch procurator of Illyria, however, most historians consider this unlikely, since Illyria was not a procuratorial province, and Plutarch probably did not speak Illyrian. Plutarch spent the last thirty years of his serving as a priest in Delphi. He thus connected part of his work with the sanctuary of Apollo, the processes of oracle-giving
